LACE-BRAIIDING MACHINE.

To all whom it mag canoe 1777.:

Be it known that I, EMIL KRENZLER, residing at Barmen, Milchstrasse 21,Rhenlsh Prussia, Germany, a subject of the Emperor of Germany, haveinvented new and useful Improvements in Lace-Braiding Machines, ofwhichthe following is a SPBClfiCtIl/MPDQ My invention has reference tobraiding or lacing machines on which are produced torchon or singlethread laces which are trimmed with laced figures or patterns and itconsists in combining with main race circles series of auxiliary circlesin such a manner that the carriers may be directly delivered from themain circles to the auxiliary race circles for braiding the figure whilein the main race circles or course the ground of the lace is carriedout. An important object obtained by my invention is that the newmachine is very simple in construction and operation.

The essential features of the inventlon and of its practical applicationare fully described in connection with the accompanying drawings.

In the said drawings Figure 1 showsin a plan view part of the top plateof the machine.

Fig. 2 is a section along line AA of Fig. 1.

Fig. 3 is a top view showing in skeleton lines the complete arrangementof the raceimilar letters of reference indicate corre sponding parts.

The machine consists asusually of the top plate 1, and the bottom plate2, which are united by means of the pillars 3 that carry theintermeshing drive gears f. The heads of the latter are connected in anysuitable manner to the main race circles or carrier engaging drivers 0;which are directly located in the bed plate 1 as shown. In connectionwith these main race circles a are arranged according to my inventionseries of auxiliary race circles b in such a manner that each series mayform a special braiding course and may be each connected with anadjoining main race circle a so that the carriers may be guided directlyfrom a main race circle a toitscooperating auxiliary race circle 7) forthe purpose of braiding thereon the pattern while at the same time thecarriers on the main race circles are shaping or braiding the ground ofthe lace.

As will be seen from Fig. 3 each'group ofcles may be of uniformdiameter.

main and auxiliary race circles is arranged in a straight line in orderthat all race cir- For delivering at any time the carriers from the mainrace circles a to the circles b and vice versa both cooperating racecircles a, b are provided with four horned drivers it, 5 as shown whiletheremaining main race circles c are fitted with two horned drivers 6.The drivers 4 and 5 are provided with four horns, since each of thedrivers cooperates with at least three adj acent drivers, in catchingthe carriers and, passing the same from one race circle to the other.The drivers 6 which cooperate with two drivers or their adjacentdrivers, during the operation of the machine, are provided with only twohorns, the same being located on opposite sides thereof to allow thehorns of the adj acentdrivers to cooperate every half turn of thedrivers 6. The movement, arresting and governing of the carriers iseffected in a known manner by means of the gears f on the shafts orpillars 3; said gears are made to engage the coupling members g, 9 thesaid member 9 being seized by a fork g seated on a vertical shaft thatis journaled in the plates 1, 2 and upon which bears a spring is whichseparates the members g, 9 By drawing the said shaft g by means of theangle levers c and rods h, 71 through the jacquard machine or any otherpattern apparatus the members g, g are connected and the drivers arerotated. The rods 72. are connected in a known manner with the mainpattern apparatus which makes periodically half a turn and the rods 2'are connected with an additional pattern apparatus which works in theintervals so that they operate the coupling members g, 9 every quarterturn of a driver and according to this mode of working the partlyconically shaped ring socket 0 of the drivers 4, 5 is provided withrecesses m into which fits the end of a rigid piece n fastened to thebed plate Z. It will be seen that' a locking device of this kind maybeoperated to lock the carriers after and for each quarter turn of thedrivers. Instead of employing two successively working patternapparatuses, only one may be used.

Between four adjacent main and auxiliary circles is fastened under thebed plate 1 on a I cles, the carriers used in my machine are providedWith a pin or projection 1" which sliding along the guide piece p holdsthe said carrier in contact or engagement with the respective driver. Incaseof braiding special patterns the drivers I) may be' fitted with lessthan four horns." As stated above A lace braiding machine comprising achain of main race circles having tvv0-' horned drivers, a chain ofauxiliary race Copies of this lpatent may beobtained for five'centseach, by addressing the Commissioner of Patents circles interposed inthe chain of Inainrace circles, said auxihary race circles havlng-four-h0rned drivers, a chain of race circles alongside said auxiliaryrace circles andhaveach quarter turn thereof.
